LUBBICATING DEVICE Application filed April 12, 1928. Serial No. 269,450.

12 which is threadedly associated therewith. The base 1s further provided with a conduit This invention relates-to lubricating devices, andcomprehen'ds an improved lubricatorwhic'h insures a uniform feed of the lubricant to the part or parts to be lubricated. 5 The invention furthermore contem'platesa lubricator including means for rendering the uniform feed adjustable or capableof regulation. p

More specifically, the invention comprehends a lubricating device which includes a lubricant well from which a capillary feeding element immersed in the lubricant, leads to the'parts to be lubricated and in which a lubricant reservoir is employed, the same. being provided with an outlet submerged in the lubricant for maintaining a constant level in the well whereby uniform feed of the lubricant is obtained.

The invention furthermore resides in means for adjusting the outlet with respect to the well for regulatingthe level of the lubricant in the well in order to increase an decrease theflow of lubricant through the capillary element.

Other objects of the invention reside in the comparative simplicity of constructionand mode of use of the device, the economy with which it may beproduced and installed and the general efficiency derved therefrom.

With the above recite and other objects in view, reference is had to the following description and accompanying drawings, in which thereis exhibited one example or embodiment of J the invention, while the claim defines'the actual scope of the same.

In the drawings: a Figure 1 is a vertical sectional view through the lubricating device.

Figure 2 is a sectional ably clo ed at its'upper open end by a cover v plan view thereof taken approximatelyon the line 2-2 of Figtion where the or passage having a vertical portion 13 communicating with the well 11 adjacent the upper end and the lubricant to above the maximum level of be received by the well. The

conduit is provided atits lower end with a communicating horizontal portion 14 which leads into a chamber 15 having a depending boss 16 for attachment to lubricated. At the juncture of t portion 14 with the the part to be e conduit chamber, a valve seat 17 is-provided with which a valve element 18 is adapted to cooperate for flow of lubricant from the chamber 15. The valve element 18 is pro-' 19 projecting laterally The boss 20 is provided vided with a stem through a boss 20.

"cutting ed the conduit to the with a removable plug 21 constituting a bearing element for the stem 19 and as a seat for one end of a coiled expansion spring 22, the

the valve element 18 with the end of-which engages an abutment 23 on the stem to movethe effect engagement of seat 17. The

lug 21 is formed. with radial grooves 24;

while the stem pin 25. When pin register or a spring functions is provided with a transverse the stem is rotated to a posirojecting terminals of the ign withthe grooves 24, the to axially project the valve stem in a direction. to engage the valve ele ment 18 with the seat 17. The valve stem is provided at its outer" free end with a manipulating head 26 which affords means for exerting an outward pull for turning the same on the stem and to 'a position where the protruding portions of the pin 25 are out of alignment or registry with the grooves, therey unseat the valve element holding the valve stem in a position to 18 from the seat 17,

againstthe action of the spring 22. I

A capillary element such as tends upwardl .th'rough the 13 of the con uitand into its end immersed in therein. A reservoir consistin of o of In ricant L is feed lubricant to tainer 28 holding a' supply designed to gravitationally the well 11 in such a manner.

a wick 27 exvertical portion the well 11 with the lubricant contained that a predeterwhich is suitably sealed in place mined level of the lubricant is maintained in chamber 15 and thence through the boss to I the parts to be lubricated:

In View of the fact that it is desirable to regulate or govern the feed suitable means is accorded for varying the level of the lubricant in the well. Obviously, this maybe accomplished in various ways, but for the hr poses of illustration of one manner in w ich it may be accomplished, the outlet neck 29 of the reservoir is shown as provided with external threads 30 which engage within the threaded opening 31 of the cover 12 of the well and a lock nut 32 is threadedly engaged on the neck for retaining the neck in its vertically adjusted positions. In order to facili tate manipulation of the nut, the same is provided with a radially projecting handle 33 which extends outwardly a suflicient distance beyond the cover to allow for grasping and manipulation thereof. The outlet neck 29 as illustrated is formed as a part of a removable closure cap 34 having an internally threaded flange 35 which engages over the threaded portion 36 of the container 28 and by means of a gasket 37,

In use and operation, the flow of feed of lubricant through the wick .or capillary element 27 is decreased by loweringvthe level of the lubricant in the well 11 and is increasedby'raising the level as illustrated in Figure 3 of the drawings. It will thus he s en that an adjustable uniform feed for lubricators has been devised which insures when adjusted a positive uniform feed of lubricant to a part to be lubricated:

What is claimed is:

A lubricating device including a base de fining a lubricant well having a downwardly directed conduit opening at its upper end into the well above the maximum level of the lubricant contained therein, a capillary feeding element extending through the conduit and immersed in the lubricant in the well and,

a closed lubricantreservoir having a depend ing exteriorly threaded outlet nozzle thread edly engaged with the base to dispose its outs let end in the well, saidreservoir being vet-ti cally adjustable by turning movement thereof with respect to the base to raise and lower the level of the lubricant in'the well whereby to increase and decrease the feed of the lubricant by the capillary element and a lock nut threadedly engaging the outlet nozzle for impinging against the threaded portion of the base to retain matinee the reservoir in its vertically adjusted positions.=
